I thought of something similar too. But I'm far away from 330Mhz pixel clock.
I'm just using LCD standard timings, which result in a pixel clock of
304.37MHz:

I also had the suspicion that the magic 300Mhz mark might be a problem, so I
created a resolution with custom timings for 74Hz which resulted in ~295MHz,
but the issue was still the same. It seems like it's really just about the
refresh rate and not the timings or pixelclock.
